KKnD, or Krush, Kill 'n' Destroy is a series of post-apocalyptic real-time strategy games by Beam Software. KKnD was released in 1997, while a sequel - KKND2: Krossfire was released in 1998. Towards the end of 1997, KKnD Xtreme, an expanded version of the original was released, which featured extra missions and enhancements.
All games in the series feature a campaign for each of the different factions in each game, alongside multiplayer capabilities.
The year 2079 AD realized Mankind's ultimate nightmare: an all-out nuclear war exterminates a quarter of the world's population almost instantly. Infrastructure collapses, as mutagenic viruses infect humans and animals alike. Most of the survivors of the attack (aptly named the Survivors) live underground, but those who don't are mutated by the viruses and nuclear fallout (what they call the Evolved). 2141 saw the underground dwellers breaking through the surface after living underground for decades. Soon enough, the "Evolved" and "Survivors" will meet.
The gameplay in the KKnD series is similar to that of other real time strategy games, such as Command & Conquer and StarCraft, created by Westwood and Blizzard respectively. The player uses resources to manufacture buildings which can create units and vehicles, which are used to exterminate opposing forces. Like the Z series of games, KKnD is tongue-in-cheek, not taking itself too seriously.
In KKnD and KKnD Xtreme, the player can choose from either the "Survivors", humans with access to technology, or the "Evolved", mutant survivors of the nuclear blasts. In KKnD 2: Krossfire, an army of technologically advanced robots are also available, the "Series 9". Each army has a selection of units and vehicles, though they fall into equivalent groups.
